style: format code for consistency

- Ensure consistent use of double quotes for strings in the
  Gemfile and sitemap configuration files.
- Add spaces for better readability in array declarations
  within the RefreshSitemapWorker.

These changes improve the readability of the code without
changing any functionality. Adhering to a consistent coding
style helps maintainability and team collaboration.
